William Herschel (William? Herschel，? 1738-1822), a British astronomer, the founder of stellar astronomy, is known as the father of stellar astronomy. ? Herschel's greatest contribution is the study of the structure of the Milky Way. He was the first person to determine the shape, size and number of stars of the Milky Way.

For William Herschel, his indissoluble bond with telescopes and astronomy actually benefited from music. William Herschel's father, Isaac, is also an oboe player and plays in the Guards Orchestra. William learned violin from his father at the age of 4, and learned to play oboe when he was a little older. My father used to teach music theory textbooks, including Harmony Acoustics by Smith. According to the clues provided by the book, William found Smith's other monograph, Complete Optical System, and mastered the basic knowledge of telescopes very early. And old Isaac is versatile. While teaching his children music at night, he often helps them know the starry sky, but he has an unexpected harvest. ? Following in his father's footsteps, 16-year-old William was forced to drop out of school to reduce his family's burden and joined the orchestra to play the oboe. In 1756, the "Seven Years' War" broke out between Britain and France, with Prussia on the side of Britain and Austria and Russia on the side of France. William couldn't bear the pain of the war, and in the following year he crossed the sea alone to escape from London. In order to escape arrest, he changed his name and surname and hid in Tibet. Because I don't know English, I am sparsely populated and penniless, so I have to live by playing musical instruments and teaching music. When his life is a little stable, he engages in music during the day, studies astronomy and grinds telescopes at night, and insists on watching the sky for his own entertainment on sunny nights. In 1781, William discovered Uranus < P > with a telescope of about 2.1 meters. Therefore, his lifelong contribution to astronomy is only a musician, and there are no musical works handed down from generation to generation.
